GECO HP HAIL-PROOF

hail-proof waterproofing membrane

Pre-fabricated waterproofing membrane made of distilled bitumen and elastomeric polymers (SBS) having a woven non woven single strand composite polyester reinforcement, which provide the membrane with high mechanical characteristics and excellent dimensional stability. The upper face is self-protected with mineral slates which reduce superficial heat absorption improving the durability of the membrane. The self-protected versions have a side selvedge of 10 cm and upon request a head selvedge of 15 cm, to improve adhesion between the sheets. The high elasticity of the SBS-type compound with flexibility at low temperatures up to -25°C is ideal for ensuring optimum adhesion to the support and for best impact resistance. The reinforcement of the spunbonded polyester fibre nonwoven fabric with elevated mechanical properties and excellent dimensional stability is perfect for coverings subject to dimensional variations. Additionally, the elevated bulk of the reinforcement allows for the obtaining of excellent puncture resistance. The thickness of 4 mm measured on the selvedge allows utilisation in a single layer and increases the impact resistance. The self-protection in mineral slate allows for utilization as a top layer and increases resistance to cutting caused by hail.
